UNITED STATES PATENT OFFICE.

STAMP OR SEAL.

proved Stamps or Seals, of which the following is a specfication.

This invention relates to a new and useful improvement in a stamp orseal, and has for its principal object the provision of a combination ofdevices in such an apparatus, permitting the same to be changed .so thatthe central part may consist of a special and characteristic design,such as thumb-print, portrait, and the like, which may be readilyremoved and changed at will.

The value of a digital impression for Men tification is well known, andit is the general practice to produce the impression from the thumb orfinger itself, but in order to utilize such an impression in combinationwith other devices to form a characteristic seal, it is inconvenient tomake the impression directly, since it would be very diflicult topreserve always the same relative position between such impression andthe other parts of the design, and to prevent the digital impressionfrom impinging and partially obliterating the other parts of theimpression of the stamp or seal.

1 accomplish the purposes of this invention by means of the hereinafterdescribed combination of parts forming a complete stamp or seal, apreferred form of which is illustrated in the accompanying drawings, inwhich:

Figure 1 is a plan view seen from above; Fig. 2 a vertical section ofthe main part or body of the apparatus showing the central movablecarrier advanced to the proper position for removing and changing thedigital impression stamp or other similar part; Fig. 3 is a verticalsection of said removable part; Fig. 4 is a reversed view of the centralstamp-holder; Fig. 5 a plan view of the face of the same; and Fig. 6 avertical section of the same; Fig. 7 is a perspective view of thecomplete apparatus; Figs. 8, 9, 10 and 11 are details hereinafterexplained; Fig. 12 a plan or base view of the complete apparatus; andFig. 13 a view of the body of the apparatus with the central carrier forthe removable device placed on a level with the printing surface of thestamp, ready to make impressions.

'As will be seen from the said drawings,

Specification of Letters Patent.

Patented July 26-, 1921.

Application filed March 12, 1920. Serial No. 365,304.

the apparatus consists of a handle, a, whereon is screwed or otherwisesuitably mounted the head orprincipal part of the apparatus, (Figs. 2and 13) comprising a spring controlled part or removable design carrier-Z) mounted in a circular seat of the frame 0 and having its shanksurrounded by a spiral spring which normally acts to cause the carrierZ) to emerge from its seating and take the position shown in Fig. 2,whereas by pressure on the face of the movable part Z) it will be'movedto the position shown in Fig. 13, where it is retained by a catch leverd in combination with adjusting screw 6. The face of the carrier Z) isprovided with a suitable dove-tail slot wherein may be introduced thecorrespondingly formed slide 9 (Fig. 3) on the surface of which isengraved the digital impression or other design forming the changeablepart ofthe stamp or seal.

The main body or head-frame e is provided with an outer annular part itwhereon is engraved the permanent-or stationary part of the stamp orseal design; with the setscrew Z which holds the latter firmly in placewhen in the operative position; and with the ilitel'lOl thread is forfastening to the hand e a.

Operation? Grasping the stamp by the handle a with the left hand so thatthe thumb rests on the catch (Z and with the stamp in vertical position,base upward and the set screw Z toward the right; loosen the latterallowing the sliding carrier Z) to protrude under the influence of thespring f; place the slide 9 containing the removable design in thedove-tail slot of the carrier 6 press down the catch (Z and press thecarrier 2) into its place in annular part h and tighten the setscrew Zthen place the stamp face downward on a smooth surface, such as a glass,table, or the like, and again releasing the set-screw Z, the spring fwill cause the printing surface of the slide 9 to" be exactly leveledwith the stationary printing ring it, where it may then be finallysecured by means of the set-screw Z, the stamp being now ready for use.I

It is contemplated by the inventor that the removable slide 9 containingthe thumbrint or other individual characteristic is to be retained'inthe possession of its owner,

I for which purpose a small pocket case may be like ma make use of acommon stain J or 7 1 seal, addlng thereto lllS individualcharacteristic 1m )l'QSSlOIl consistin of a di ital 11n- I 1 b s oprcssion, portrait, or any other design which he may prefer; althoughthe main idea of the seal is to permit the use of a thumb-print incombination with a seal, and as such a use is novel according to theinformation and belief of the inventor, it is herein especially claimedregardless of the form of construction used, which as given in thedrawing is by way of example solely.

Having thus described myinvention, what I claim and desire to protect byLetters Patent of the United States of America, is:

1.' In a stamp or seal, the combination of a printing surface composedof a permanent or stationary part and a removable or changeable part,means for removing or changing the said removable or changeable part,means for holding in operative position thesaid movable part, and meansconsisting of a sliding carrier whereby the changeable part may beprotruded above the level of the permanent orinting surface part and thechangeable part removed or introduced in said carrier.

2. In a stamp or seal the combination of a printing surface comprisingan'outer annular permanent part, and an inner circular removable part,means for removing or changing the said removable or changeable part,means for holding inoperative position the said movable part, and meansconsisting of a sliding carrier whereby the changeable inner circularpart may be protruded above the. level of the outer fixed annular partand the changeable part removed I 4. A stamp or seal comprising thecombiprinting design, substantially asdenation of a head or principalpart provided with an outer annular stationary printing surface, aprinting design engraved on said surface, a sliding device disposed tomove reciprocally in the central part of the said head and having itsouter surface slotted wherein to place a removable slide or disk, aprinting design consisting of a thumb or digital print on the surface ofsaid slide or disk, said slide or disk being removable when protrudedabove the level of thesaid stationary printing design, substantially asdescribed.
